Molecules of the the title compound, C21H24Cl2N2O2, are located on a twofold rotation axis, which passes through the C atom linking the two N atoms. Two intramolecular O—H...N hydrogen bonds were observed. In the crystal, non-classical intermolecular C—H...O hydrogen bonds link the molecules into chains along the a axis. The crystal studied was a racemic twin.
